我的Spring Web模型 - 视图 - 控制器(MVC)框架中有这个类。 Spring Web模型 - 视图 - 控制器(MVC)框架的版本是3.2.8。
我有这个web.xml文件。
...
<servlet-mapping>
<servlet-name>ecolabelWeb</servlet-name>
<url-pattern>*.do</url-pattern>
<url-pattern>/newdesign/manage/manageapplications</url-pattern>
<url-pattern>/newdesign/manage/manageapplications/</url-pattern>
<url-pattern>/newdesign/manage/manageapplications/*</url-pattern>
<url-pattern>/newdesign/manage/home</url-pattern>
<url-pattern>/newdesign/manage/home/</url-pattern>
<url-pattern>/newdesign/manage/home/*</url-pattern>
<!-- Explicitly mention /welcome.do for usage as welcome page -->
<url-pattern>/welcome/welcome.do</url-pattern>
</servlet-mapping>
...
和这个控制器:
/**
*
*/
@RequestMapping(value = { "/newdesign/manage/home",
"/newdesign/manage/home/",
"/newdesign/manage/manageapplications",
"/newdesign/manage/manageapplications/"}, method = {RequestMethod.GET})
public String manageApplications (@ModelAttribute("aplicationListForm") final AplicationListForm aplicationListForm,
HttpServletRequest request,
Model model ) throws ExecutionException {
User sessionUser = (User)request.getSession().getAttribute(Const.SESSION_USER);
..
}
此网址正常
/newdesign/manage/manageapplications
但是这一个newdesign/manage/home
我收到了这个错误
WARNING: No mapping found for HTTP request with URI [/devices/newdesign/manage/home]
我真的疯了!
我也尝试将它放在另一个具有相同结果的方法中
@RequestMapping(value = { "/newdesign/manage/home",
"/newdesign/manage/home/"}, method = {RequestMethod.GET})
public String cbHome (Model model ) throws ExecutionException {
..
}
此网址正常运行 http://127.0.0.1:7001/devices/newdesign/manage/manageapplications 不是这个(?!) http://127.0.0.1:7001/devices/newdesign/manage/home
答案 0 :(得分:0)
您的配置无效,因为在您的web.xml中,您的应用程序仅限于使用这些网址:
<url-pattern>/newdesign/manage/manageapplications</url-pattern>
<url-pattern>/newdesign/manage/manageapplications/</url-pattern>
<url-pattern>/newdesign/manage/manageapplications/*</url-pattern>
这是一个典型的web.xml:
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
使用此配置,您告诉Spring使用dispatcher servlet机制来处理传入请求和视图呈现。通过这种方式,他可以处理您在控制器中定义的所有URL,例如/newdesign/manage/home
。
您需要创建用于配置调度程序的dispatcher-servlet.xml
文件。
